Here are today’s solar images taken from Al Sadeem Observatory, September 28, 2020.
The sky was mostly clear with intermittent light to moderate breeze which provided good transparency but average seeing at the time these images were taken.
AR2773 has completely decayed its sunspot structure yesterday, September 27, 2020. Meanwhile, a small area of pores was spotted developing near past-meridian at the Sun’s southern hemisphere. no sunspot number designation yet;. The latest sunspot number (based on visual count and Wolf number calculation) is 3. Other than that, not many significant going on with the Sun lately aside from a moderately huge eruptive prominence at the northeastern limb, and the remnant enhanced plages associated with former AR2773 as the only noteworthy visible solar features distinctively captured in H-alpha imagery.
Space weather agencies* forecast solar activity to be at very low levels with chances of weak X-ray fluxes or flares up to B-class (possibly up to isolated C-class) intensity, mainly from AR2773. Close monitoring is being conducted by numerous space weather agencies for any significant development.
Equipment used are Skywatcher 120mm refractor telescope with Baader filter and unmodified Canon EOS 1D Mark IV DSLR camera for visible imagery. For H-alpha imagery, the equipment used are Lunt 60mm H-alpha solar telescope, and QHYCCD290III mono camera; all mounted on Skywatcher EQ6 pro mount Pre-processing of visible solar images was performed in PIPP, stacking in Autostakkert, slight wavelet adjustments in Registax 6, and post-processing in Adobe Photoshop CC.
